PNEUMATIC TOY.

Application filed February 10, 1922.

T all to ham it may concern:

Be it known that I, HANS LARSEN, a citizen of the United States, andresident of Racine, in the county of Racine and State of Wisconsin,have, invented certain new and useful Improvements in Pneumatic Toys;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates to pneumatic toys which are especially designed forthe amusement of young children.

The general object of the invention is to construct a device of thiskind which may be inexpensively made,'but one which will be strong anddurable.

- section.

t is also an object of the invention to provide improved means by whichthe toy may be easily filled with air under pressure whenever the samebecomes deflated.

A still further object of the invention is to provide a toy of thisnature with a simple and improved whistling element.

The toy in which my invention is embodied will be described inconnection with the accompanying drawing, in which- Figure 1 is a frontelevation of the invention, and

Figure 2 is a similar view but having a part thereof broken away andshown in The toy is formed with two eXpa-nsible body portions 5 and 6,constructed from rubher, or the like, and connected by a constrictedneck 7, within which is fitted a plug 8, the neck portion being heldtightly against the peripheral portion of the plug by a string 9, whichis wound about the same, or by any other suitable means. The plug 8 ispreferably formed with two passages 10 and 11, extending therethru andforming means of forcin air or other gas contained within the bodyportions, from one of said portions to theother; These passage ways arecontrolled by oppositely disposed check valves 12 and 13, which arepreferably in the shape of rubber flaps, and aid in producing awhistling sound when the air passes thru said passage ways. One or bothof the body portions may be decorated with a suitable design 14, whichwill Serial No. 535,521.

be distended, as shown in dotted lines in Figure 1, to presentagrotesque appearance whenever the other body portion is squeezed.

For the purpose of inflating the toy, one of the body portions, as forexample the portion 6, is provided with an opening thru which extends aplug 15, a neck 16 being formed around the opening and tightly securedto the plug by means of a. string 17 or other suitable fastening device.The in ner end of the plug preferably extends some distance within theinterior of the body portion, and a duct 18 extends therethru and hasits inner end deflected so that it opens 'thru the side wall of theplug.

A sleeve 19, preferably of rubber, is stretched around the plug 15 tocover the inner end of the duct 18, and preferably extends between theplug and the neck 16 so that it may be firmly secured in place.

it will be seen that when air or other gas is blown thru the duct 18into the body portion 6, the sleeve 19 will yield to permit the gas toreadily pass in, but will form an effective check to prevent deflation.

lVhile I have shown and described specifically one form in which myinvention may be embodied, it will be of course understood that variousmodifications may be made therein, without departing from the spirit ofthe invention.

I claim:

The combination with a pneumatic toy comprising a body portion having anopening surrounded by outwardly projecting flanges, of aplug securedwithin said opening, said plug having a smooth cylindrical surface andhaving a duct extending longitudinally inwardly from its outer end andterminating in a laterally extending aperture, an elastic slee esurrounding the plug and yieldably covering the inner end of the duct,and a binding element surrounding said flanges and binding said flangesagainst said sleeve and said sleeve against said plug.

In testimony that I claim the foregoing I have hereunto set my hand atRacine, in the county of Racine and'State of Wiscon- HANS LARSEN.
